Attribute-Based Access Control(ABAC) with Decentralized Identifier in the Blockchain-Based Energy Transaction Platform

Abstract

With the development of ICT technology, it has also been applied to the power grid, but as a target of hackers' attack, a security solution to protect the power grid is being studied. Attribute-based Access Control (ABAC) is one of the most commonly used security solutions by providing granular and flexible access control, but it threatens privacy because it determines access control based on user attribute values. With user privacy emerging as a new topic, Decentralized Identity(DID) is emerging as a new alternative for protecting user privacy. In this paper, we propose a DID-based ABAC to solve the problem of ABAC's privacy exposure and apply it to a power transaction platform.
